migration to 6 and hostname issues

When I set the system up, I had a hostname issue, and ended up going into a whole slew of LDAP config files to change my hostname. Naturally, not everything is working.

I'd like to solve all my problems, and upgrade to 6 at the same time. Is the following a valid path to follow to migrate to a new server while retaining all user info (calendars, email, etc).

1. install 5.0.14 on a new server with new hostname
2. do a backup of the original server
3. restore the original server onto the new server
4. run for a few days
5. upgrade to 5.0.18
6. upgrade to 6.0

I'd like to do a 32 bit to 64 bit upgrade at the same time, but I'm afraid I'd be doing too much.

You should never need to hack LDAP files due to hostname issues. They all stem from mis-configured files and DNS when ZCS is initially installed. You would be better to fix that first before proceeding with a upgrade.
